The real-time system put forward here is a soft real-time system based on Windows NT. Preemptive multitasking mechanism is used on NT, in this way, the beyond-visual-range and real-time transmission of the TIS and command/control information can be realized via data link relayed by synchronous satellite.

实现的实时系统是一个基于Windows NT的弱实时系统，它通过在NT上采用多任务抢占机制以及同步卫星为中继的数据链路实现了TIS信息和指控信息的超视距实时传输，解决了信息的超视距实时传输问题。

A preemptive multitasking OS, such as UNIX/Linux, Windows NT/2000 or OS/2, frees up resources when ordered to by the operating system, on a time-slice basis, or a priority basis, so that one application is unable to hog resources when they are needed by another program.

抢先式多任务 OS（例如 UNIX/Linux、Windows NT/2000 或 OS/2）中，操作系统基于时间片或基于优先级命令应用程序释放资源时，应用程序释放资源，以便在其它程序需要资源时，正在使用这些资源的应用程序不会独占它们。

From the outset it had preemptive multitasking, a graphical user interface, shared libraries, messaging, scripting, and multiple simultaneous command line coles.

C/OS-Ⅱ,the Real-time kernel is a highly portable, ROMable, very scalable, preemptive real-time, multitasking kernel for microprocessors and microcontrollers.

C/OS-Ⅱ是一种可移植、可固化、可裁剪及可剥夺型的多任务实时操作系统，适用于各种微处理器和微控制器。

Secondly, the paper introduced how to implement safety detection by ultrasonic sensor, and presented systemically all the design of collecting and processing signals, storage circuit, lithium battery charging and discharging circuit, data communication circuit, keypads and LCD. This paper studied the code of uC/OS-II and introduced how to port uC/OS-II onto LPC2214. The Real-Time Kernel uC/OS-II is a highly portable, ROMable, very scalable, preemptive real-time, multitasking kernel for microprocessors and microcontroller.

然后论文具体介绍了如何实现超声波传感器进行实时安全监测，并系统的介绍了超声波监测系统的信号采集，处理，存储电路，锂电池充放电控制电路，数据通讯电路，键盘，显示器等的设计；也详细的介绍了多任务操作系统uC/OS-II的源代码及如何在LPC2214上移植等。uC/OS-II是一个移植方便的、可固化的、可裁剪的、占先的多任务实时内核。

C/OS-II, The Real-Time Kernel is a highly portable, ROMable, very scalable, preemptive real-time, multitasking kernel for microprocessors and microcontrollers.

在构建的硬件平台基础上完成了内核引导程序的实现，完成了μC/OS-Ⅱ操作系统在ARM7上的移植，对μC/OS-Ⅱ操作系统本身进行了扩充，实现了一个相对完整、实用的嵌入式实时多任务操作系统。

Second, after looking into different definitions of shareholder's preemptive right, the author convinced the definition of shareholder's preemptive right as a right that additional shares shall not be issued without first offering to all existing shareholders having similar rights a reasonable opportunity to take ratable amounts of the additional shares.
